E-Fan

It is as clean as a butterfly and hums like a bee: with a 600-kilogram weight and a maximum speed of 160 km/h, E-Fan is the first aircraft with fans to have fully electric propulsion. The plane has zero carbon-dioxide emissions in flight and is significantly quiterer than a conventionally powered aircraft. Source: Airbus Group.
